Assembling the Bedbar
1. Install the bedbar, positioning the mounting ears
between the washer and the bedbar adjuster.
2. Secure the bedbar to each side plate with the bedbar
bolts (nuts on bolts) and the 6 washers.
Note:
Position a nylon washer on the each side of
the side-plate boss. Place a steel washer outside of the
outer nylon washers (
Figure 31 ).
3. Torque the bedbar bolts to 27 to 36 N∙m (240 to 320
in-lb).
4. Tighten the locknuts equally on each side until the outer
steel washers cannot be rotated by hand. Then loosen
the locknuts until the outer steel washers just rotate by
hand, yet there is no bedbar end play (
Figure 32 ).
Note:
Overtightening the locknuts can deflect the side
plates and the bedbar, which can affect reel-to-bedknife
contact.
Note:
The washers on the inside may have a gap.
Note:
Do not overtighten the nuts, as damage to the
spring may occur.

Servicing the HD Dual Point
Adjusters (DPA)
1. Remove all parts; refer to Installation Instructions for HD
DPA Kit Model 120-7230 and to Figure 33 .
2. Apply anti-seize compound to the inside of the bushing
area on the center cutting unit frame (
Figure 33 ).
3. Align the keys on the flange bushings to the slots in the
frame and install the bushings (
Figure 33 ).
4. Install a wave washer onto the adjuster shaft and slide
the adjuster shaft into the flange bushings in the frame
of the cutting unit (
Figure 33 ).
5. Secure the adjuster shaft with a flat washer and a
locknut (
Figure 33 ). Torque the locknut to 20 to 27
N∙m (15 to 20 ft-lb).
Note:
The bedbar-adjuster shaft has left-hand threads.
6. Apply anti-seize compound to the threads of the
bedbar-adjuster screw that fits into the adjuster shaft.
Thread the bedbar-adjuster screw into the adjuster
shaft.
7. Loosely install the hardened washer, spring, and spring
tension nut onto the adjuster screw.
8. Install the bedbar, positioning the mounting ears
between the washer and the bedbar adjuster.
9. Secure the bedbar to each side plate with the bedbar
bolts (nuts on bolts) and 6 washers as follows:
A. Position a nylon washer on each side of the
side-plate boss.
B. Place a steel washer outside each of the nylon
washers (
Figure 33 ).
C. Torque the bedbar bolts to 37 to 45 N∙m (27 to
33 ft-lb).
D. Tighten the locknuts until the outside steel washer
stops rotating and end play is removed, but do not
overtighten or deflect the side plates.
Note:
The washers on the inside may have a gap
( Figure 31 ).
10. Tighten the nut on each bedbar adjuster assembly
until the compression spring is fully compressed, then
loosen the nut 1/2 turn (
Figure 32 ).
11. Repeat the procedure on the other end of the cutting
unit.
12. Adjust the bedknife to the reel.
